Hello everyone, I am a blockchain developer in Shanghai. Looking back, in 2020, I was just a freshly graduated coder, confusedly getting caught up in the whirlpool of cryptocurrency. At that time, Ethereum's gas fees skyrocketed like a roller coaster to $200 per transaction. I tried to swap some ETH on Uniswap, but after half an hour, all I had was a pile of anxiety in my wallet. It was then that I first heard the name 'Polygon.' It was still called Matic Network back then, an unremarkable sidechain solution that sounded like a cheap patch to help Ethereum fix its congestion issues. I thought to myself, could this thing really go somewhere? Who knew, five years later, today in 2025, Polygon has quietly transformed into the 'invisible highway' in my digital wallet—an artery connecting countless chains and carrying trillions of dollars in liquidity. It's low-key, not flashy like Solana, nor does it rely on storytelling like Optimism, but it is the 'quantum entangler' of Web3, seamlessly entangling all chains in the background, unleashing unprecedented efficiency.
